the 1999 McClaren Emergency safety kit for drivers
it included jumper cables, a 1 gallon fuel can with disposable bladders, air compressor, siphon pump, reflective triangle, tow strap, flashlight, flares, first aid kit, fuses, lock thaw, leatherman, latex gloves, coveralls, piloce aid sign, handwipes, and a rag. All fitting in a spare tire area.
Know what else should be in there? A hand crank radio to listen to while you wait for a ride, 100 dollars, a credit card, a twinkie and a YooHoo.
